　また、本技術は、光源８は、導光部７の光出射部７ａから出射される光の輝度分布において、分布の谷に対応する位置に配置される。これにより、より均一な明るさで、装飾部５を光らせることができ、デザイン上の商品価値を高めることができる。 Further, in the present technology, the light source 8 is disposed at a position corresponding to the valley of the distribution of the luminance of the light emitted from the light emitting portion 7 a of the light guide 7. Thereby, the decorative portion 5 can be illuminated with more uniform brightness, and the commercial value on the design can be enhanced.
　以上のように、本開示における技術の例示として、実施の形態を説明した。そのために、添付図面および詳細な説明を提供した。 As described above, the embodiment has been described as an example of the technology in the present disclosure. For that purpose, the attached drawings and the detailed description are provided.
　したがって、添付図面および詳細な説明に記載された構成要素の中には、課題解決のために必須な構成要素だけでなく、上記技術を例示するために、課題解決のためには必須でない構成要素も含まれ得る。そのため、それらの必須ではない構成要素が添付図面や詳細な説明に記載されていることをもって、直ちに、それらの必須ではない構成要素が必須であるとの認定をするべきではない。 Therefore, among the components described in the attached drawings and the detailed description, not only components essential for solving the problem but also components not essential for solving the problem in order to exemplify the above-mentioned technology May also be included. Therefore, the fact that those non-essential components are described in the attached drawings and the detailed description should not immediately mean that those non-essential components are essential.
　また、上述の実施の形態は、本開示における技術を例示するためのものであるから、請求の範囲またはその均等の範囲において種々の変更、置き換え、付加、省略などを行うことができる。 Moreover, since the above-mentioned embodiment is for illustrating the technique in this indication, various change, substitution, addition, omission, etc. can be performed within the range of a claim or its equivalent.
　以上のように本技術は、電子機器のデザイン上の商品価値を高める上で有用な発明である。 As described above, the present technology is an invention useful for enhancing the commercial value of electronic devices in design.
